Rigid Mica Sheet yog dab tsi?
Rigid mica daim ntawv yog cov khoom siv engineering siab heev uas tsim los ntawm85–90% siab- zoo mica ntxhiabonded nrog siab -kub-resistant silicone resin.
Raws li ib txwm muaj aluminosilicate ntxhia uas muaj cov poov tshuaj, hlau, magnesium, thiab hydroxyl pawg, mica muab lub hauv paus tseem ceeb rau cov khoom siv rwb thaiv tsev siab no.
Rigid mica sheets yog raws li ob hom ntawm mica:muscovitethiabphlogopite, txhua qhov muab cov txiaj ntsig sib txawv rau cov phiaj xwm siv.Muscovite ua tau zoo hauv cov ntawv thov hluav taws xob vim nws lub zog dielectric zoo dua, thaum phlogopite muab cov cua sov ua kom zoo rau huab cua sov - ib puag ncig.
Cov txheej txheem tsim khoom suav nrog impregnating xaiv mica nrog silicone resin nyob rau hauv kev tswj xyuas. Qhov no tsim ib daim ntawv nruj, ruaj khov uas khaws cia mica qhov zoo ntawm lub ntuj thaum txhawb cov qauv kev ncaj ncees thiab kev ua haujlwm. Cov khoom kawg tuaj yeem raug txiav, zoo li tus, thiab siv thoob plaws ntau yam kev lag luam.
Cov khoom ntawm Rigid Mica Sheet
Qhov Zoo Tshaj Kub Kub Kub
Rigid mica sheets muaj qhov tshwj xeeb thermal kev ua tau zoo uas ua rau lawv sib nrug los ntawm cov khoom siv rwb thaiv tsev.
Muscovite: Kev khiav hauj lwm kub tsis tu ncua mus txog500 degree, intermittent mus txog800 degree
Phlogopite: Kev khiav hauj lwm kub tsis tu ncua mus txog700 degree, intermittent exposure mus txog1000 degree
Nws thermal conductivity yog directional:
0.3 W/m·Kperpendicular rau daim ntawv dav hlau
Mus txog3.0 W/m·Kparallel rau daim ntawv dav hlau
Cov yam ntxwv anisotropic no tso cai rau cov kws ua haujlwm kom ua kom zoo dua cov cua sov hauv kev tsim.
